The role of the SDF-2 and its crew in the Macross franchise is an ongoing one. An exposé of the SDF-2 and its crew is featured in the Macross Perfect Memory book in 1983, including information on the origin of the SDF-2 (a research vessel commissioned by the Zentraedi). In Macross Frontier, LMP-801 Ulrich Steinen mentions that he has known Sailor Uranus and Sailor Neptune since childhood, implying that they are former SDF-2 crew members (Sailor Uranus was a commander of the SDF-2). Because the SDF-2 was destroyed, there were no survivors, but future incarnations of the ship have become more advanced, including the SDF-2 Geostigma-01 and the Macross Frontier SDF-2 Kikai (a hyper-displacement prototype).
In Macross Frontier, the SDF-2 appears in several episodes, most prominently in Macross Frontier: The Movie. In this film, the SDF-2 and its crew are the protagonists in the film. It is revealed that the SDF-2 was the prototype project for the SDF-1, which was the first generation of the SDF ships.
The SDF-2 with a very large nacelle is featured prominently in Macross Frontier. In the final episodes of the show it is shown in battle with the Galaxy Train and ultimately destroyed by the Galaxy Train. A civilian anti-Macross group led by President Angelique Natsuki (a veteran of the battle with the SDF-2) builds a new SDF-2 using the Galaxy Train in order to destroy Earth. The Galaxy Train is destroyed by the SDF-2 and Angelique and her allies are killed. Their final plan, however, is foiled by Asuka and her friends, who use an experimental device to force the SDF-2 and its crew to undergo transformation and its systems to self-destruct. The SDF-2 is never seen again. However, as mentioned, the Galaxy Train is rebuilt and adapted into the new SDF-2 Kikai.
The Megaroad series is the first appearance of the Macross mecha. As was designed by the Takara company (which had previously designed the original Macross toy line), the SDF-2 mecha was larger and more sophisticated than anything else in Takara's existing toy line at that time. Its size and appearance, however, are a direct contrast to the original Macross toy line, which had more of a toy-like appearance. This is apparently a deliberate design, as the SDF-2 mecha is designed to resemble a giant spacecraft, while the original Macross toys resembled more of a mecha-style toy with the Macross characters in a more human-like form. The Macross toy line did feature a mecha style version of the mini-Macross, which was released as a bonus figure with the Macross Super Dash Go back in 1979.
The Megaroad mecha was featured in all the Macross series, having a prominent role in the original series, Macross Plus and Macross II: Lovers Again (as well as its re-edited version, Macross II: The Last Evolution), as well as a cameo in Macross Frontier. The Megaroad mecha was first redesigned for the Macross Plus OVA, and was also redesigned for Macross II: Lovers Again. It was also redesigned for Macross Frontier, which was released in 1994 in a more human-like form (with its color scheme remaining the same as the original Macross toy line). 827ec27edc
